Hi !
As file rights and protection are important on /usr,
Consider replacing #4 with :
(cd /usr && tar cf - . ) | (cd /usr2 && tar xpf -) as root
or if you prefer
still as root
dump 0uaf - /usr | (cd /usr2 && restore -rf -)
In this second way, you do not need to mount the original /usr (but in
this case you've to give the device file to dump instead of /usr)
But some people will question the reason you will move from LVM to plain
filesystem/partitioning....
